There is a web that maintains a list of geocaches with similar theme called geopuzzle. That can be for example Wooden Churches in Slovakia, Castles in Hungary, Caves in Czech, Summits in Europe etc. (http://www.geotrophy.net/en/GeoPuzzle/)
This is quite popular in Slovakia & Czech Republic. ( http://www.geotrophy.net/en/Hunters/)
There is an xml exports of the caches in particular geopuzzle. (http://www.geotrophy.net/en/development/)
The system is open, I have created 2 geopuzzle and I think this can be spread to other countries and become popular there.
My Question is Could you add this geopuzzle stats to Profile stats at project-gc?
Geopuzzle is generated also by other geo stats generators: GSAK, GeoGet, MyFound and MoziGo.
Geopuzzle stats look like in my profile: http://www.geocaching.com/profile/?u=lj.
